To all whom it may concern: v

Be it known that I, JOHN L.4 SEBASTIAN, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake i and State of Utah, have invented new and 5 useful Improvements in DeepWell Pumps,

of which the following is a specification.

The present invention relates to improve- 1 ments in deep wellpumps, the object of the invention belng to provide a pump for use pressed air under what is known as theStarrett method of pumping, as disclosed in U. S. Letters Patent to D. W. Starrett, dated May g 29th, 1906, No. 821,677, and in which, in addition to a main stream of compressed air i forcing the water or other liquid out of a chamber and upwardly in a discharge pipe, there is also employed an auxiliary'stream, or jet entering the stream of upwardly flowing liquid immediately above said chamber, so .that the column ascending in said discharge pipe, instead fof consisting wholly of liquid, consists of liquidfjand air. To apl ply this methodpractically it is necessary to employ a shifter to 'alternately direct the compressed air into one of two chambers, tb expelthe water lor other liquid therefrom into the discharge chamber, while the other chamber is being lled with water or other liquid from the well or other body of water Awhich is being pumped.' Heretofore it has not been found practicable to employ this method for pumping from deep wells owing to the dificulty of arranging the different chambers within thenarrow space ermitted in such wells. My'invention has or its object to overcome this diiiculty.

In the accompanying drawing, IFigure 1 is a broken vertical section, certain parts be-r f ing shown in side elevation, of a pump constructed in accordance with my invention; Fig. 2 is a similar section of the -upper por- -tion of the pump taken at right angles to the webs do not extend so far at their upper v and lower terminal portions as the exterior y cylinder. In the upper end of said exterior cylinder is inserted, with a tight fit, a cylindrical flange 5 of an upper head 6, comprising upper and lower transverse parallel webs 7, 8. These webs form with the flange 5 a chamber 9 which, for a reason which will hereinafter appear, I term a jet chamber. The form of this chamber is best shown in Fig. 5, and it will be seen that the chamber is not co-extensive laterally with the head, but is diminished in extent by two projections l0 from the flange 5, extending between the planes of the webs. rlhe upper web 7 is formed with a large screw-thread ed aperture 11, slightly eccentric to said head, and into which is screwed the lower i end of the discharge pipe 12, through V which the wat-er or other liquid is expelled i from the chamber 9, and with a screwl threaded aperture 13, into which is screwed A a small compressed air pipe 14, provided i with a non-return valve, indicated at 15, and discharging a jet of compressed air into 5 the chamber 9, which I therefore term the ljet chamber. Into threaded apertures 16 through said projections 10 are screwed the l lower ends of pipes 17, which are used alternately as compressed air and exhaust pipes, said pipes thus communicating respectively with chambers 18 on opposite sides of the webs 4.

The lower diaphragm is formed with a central aperture 19 and depending danges`20. each of which, as shown in Fig. 6, extends snugly around one-half of the upper edge ofx the interior cylinder 2, then in close proximity to the upper ledges of thewebs (fr, as shown at 21, and is Vthen integrally .connected to the lower portion of the cylindrical flange of the head 6, fitting snu ly, as shown at 22, against the interior sur ace of the exterior cylinder. Said portions 21 `of said ianges thus form grooves, the upper edges-of the webs 4 forming tongues, which i lit snugly in said grooves and prevent the i passage of compressed air from one 'to the 2 other of the semi-annular chambers 18 which are formed between the interior and exi terior cylinders.

The lower terminal portion of the exi terior cylinder l is formed with an annular recess 2l, terminating in an outwardly extending flange 25, to which is attached, by

lll@

.with lianges 34. The upper portion of the valve casing 32 is formed with iianges 35, which fit snugly around lthe lower edge of the interior cylinder 2. The upper edges of the webs 33 are forked or grooved, as shown at 36, to receive the lower edges of the webs 4. Below said fianges the valve casing 32 is of a form substantially square in horizontal section, and the portions of the valve casing which lie on opposite sides of the' central plane through said webs taper `inwardly downward, as shown in Fig. 1.

The lower portion of said valve casing, resting upon the packing strip 31, is formed with a diametral socket or bearing 37 to receive the knuckle V38 of a valve 39 vibratable upon a pivot pin 40, said 'valve being adapted to alternately close ports 41 in said tapering portions of the valve casing.

The fiap valves 29 on the side adjacent the inlet openings and the valve 39 on each side thereof are provided with leather facings 42 held on said valve by plates 43 screwed to thevalves.

f The following is the mode of operation of my improved pump. By means of a shifter, the construction of which forms no part of the present invention, compressed air is admitted by one of the pipes 17, say that on the left in Fig. l, while the other pipe 17 is open to exhaust. The compressed air thus admitted expels the water or other` liquid from the chamber 18 on the left through the port 41 on the left into the chamber 3 and thence into the jet chamber 9 and discharge pipe 12, compressed air being also admitted by the .jet pipe 14 into the jet chamber 9 and passing up with the water or other liquid into the discharge pipe, in the manner explained in said patentv to Starrett. The .inlet opening 30 on the left is closed by the pressure of the compressed' air in the chamber 18 on the left, but the inlet opening 30 on the right is opened by the upward pressure of the water or'liquid in the well or other body of water being pumped, which liquid fiows upwardly into the chamber 18 on the right at a rate determined by the degree of submergence of the pump. Before so much of the water or other liquid in the chamber 23 on the left has been expelled therefrom that its level 4 spectively communicatin is below the level of the port 41, the beforementioned shifter is operated, so that the compressed air flows by the pipe 17 on the right, while the pipe 17 on the left is open to exhaust. The valve 29 on the' left immediately opens, while the valve 29 on the right closes, the valve 39 swings to its position on the left, and the water or other liquid is expelled from the chamber on the right, as already explained.
